we can always revert, but not sure what to revert. if we slowed down it wasn’t caught in any benchmarks, so it would be good to know what things might feel slower
particularly what version you were upgrading from -> to if you have that
Viktor Lidholt
@vlidholt
I'll see if I can figure out there version difference. Maybe it's less well synched with the screen refresh our something

Posted an issue here: flutter/flutter#9541
Leonard B. Papilaya
@ramose
Hi all. I'm new to Flutter and Dart. Are there any tutorial how to make a listview and fill it with data from json?
Eric Seidel
@eseidelGoogle
@ramose I'm not aware of one, but https://github.com/flutter/flutter/tree/master/examples/stocks does something similar
@ramose flutter/flutter#9236 is a request for more docs along that line
Leonard B. Papilaya
@ramose
@eseidelGoogle Thanks!

@ramose I don't know much about flutter but I have done this some time ago https://github.com/charafau/u2020d
Might help

@eseidel
@ramose this person has a whole video series on flutter: https://www.youtube.com/channel/UC9EOyw-hs_rOOvKHWeJ4B2Q
@charafau let us know if you ever publish that and I’ll add it to my spreadsheet :D
Rafal Wachol
@charafau
@eseidelGoogle i didn't think about publishing it. I I've done it just to compare the 'development feeling' of many frameworks (I've done the same app with kotlin, scala, react native and flutter) :)
Eric Seidel
@eseidel
@charafau if you ever have any thoughts to share, we’d love to hear them :)
email, issues, chat, however :)
Rafal Wachol
@charafau
Sure! The biggest problem I have so far was widget positioning
I had to use many nested layouts, but that might be due to my lack of knowledge
@eseidelGoogle I was actually thinking, how hard would that be to use the engine from C ?
Eric Seidel
@eseidel
I’m not sure what that would mena?
The engine is a (relatively) small ball of C++ code: https://github.com/flutter/engine
it has 3 big pieces: the Dart Runtime, the Skia 2d graphics api, and a forked (and very stripped down) copy of Chrome’s text engine
Rafal Wachol
@charafau
I was thinking about writing small gui lib for C, rust for fun. From what I've seen all widgets are drawn in dart, but C engine is a renderer
Eric Seidel
@eseidel
The engine just knows the (C++ side of) the Dart runtime (GC, etc.), a copy of Skia (with only the hardware/opengl backend compiled in) and the stripped down text layout bits previously mentioned
if you’re writing a c/rust gui libary I doubt you’d start from Flutter’s engine :)
Rafal Wachol
@charafau
Ah, I thought I could reuse some part of it
Eric Seidel
@eseidel
we’re looking at replacing the text layout bit and that’s the only non-off-the-shelf component
well, we stripped down the dart and skia bits some, but nothing you couldn’t replicate by looking at our GN configs
I guess there is some android and iOS integration you could re-use
Writing these things is really hard, btw. :D
Mostly the pulling the whole product together is hard.
endless miles of details.
Rafal Wachol
@charafau
I know it's hard :)
I wasn't thinking about anything fancy, just for fun
Eric Seidel
@eseidel
https://github.com/eseidel/lolsim is my for-fun dart project. :D
although I don’t get a lot of time to work on it
Rafal Wachol
@charafau
I've never played LoL I'm more like a counter strike guy :D
Leonard B. Papilaya
@ramose
@charafau Thanks!
eseidel @eseidel is sad that this is 2017 and JavaScript (and thus Dart’s) regexps don’t support named capture
Eric Seidel
@eseidel
not that it really matters, but would be nice.
Rafal Wachol
@charafau
I'm waiting for web assembly ;)
Günter Zöchbauer
@zoechi
web assembly doesn't look very promising
Rafal Wachol
@charafau
Why is that ?
Günter Zöchbauer
@zoechi
haven't seen anything about web assembly that looks promising
except if you have legacy code that you want to run in the browser
Rafal Wachol
@charafau
Or maybe JavaScript will die finally ;)
Günter Zöchbauer
@zoechi
looks like the least likely outcome of all possiblities
